Abstract

Abstract: A new polymer [Cu(ox)(4,4'-bpy)]_n(1)(ox=C₂O₄^2-, 4,4'-bpy=4,4'-bipyridine) was hydrothermally synthesized and characterized via elemental analyses, IR spectrum and single crystal X-ray diffraction. The polymer crystallizes in a monoclinic system, space group Cm, a=1.1921(7) nm, b=1.153(7) nm, c=0.5155(4) nm, β=113.38(3)°, V=0.6291(7) nm³, Z=2. Cu atom in the title compound is in an octahedral geometry with four O atoms from two bis-chelating oxalate ligands in equatorial plane and two N atoms from the 4,4'-bpy ligands in the axial position. The crystal structure possesses infinite {Cu(ox)}_n chains connected with each other by the bridging 4,4'-bpy ligands in a perpendicular manner, leading to a 2D layered network with rectangular grids. The layers stacking in a staggered fashion are further assembled by C_4,4'-bpy—H…O_ox hydrogen bonds and lead to a 3D supramolecular architecture.

Key words: Hydrothermal synthesis, Copper(Ⅱ) coordination polymer, Mixed-ligand, Layered structure, Supramolecular architecture
